design of scheme for web calendar

Hi all

I want to build a web application for calendar from scratch and I want it to look like google calendar or microsoft outlook calendar (create appoiments, invite the colegues, set callback, appointments by day, week, month; being able to move appointments)


Basically, Google calendar is the case, I want to make in oracle.

For the front end, I'll use Ajax, a colleague will help me with this.

Can you tell me some directions?

to begin with, I would have just one oracle schema and each appointment should have a 'entry_by' or should I use users oracle for each user that uses my calendar?
Can I take advantage of partitioning here? or clusters?

Should what kind of questions I ask at this stage?

Thanks for your time

You don't want hundreds of patterns in a database with the same structure. It would be horribly not scalable. Each user SQL statements would be totally unsharable with other users. Blocks of caching for a user are not available for other users, etc. In addition, maintenance would be a nightmare: you'd have to make sure the upgrade scripts have been applied to hundreds of patterns whenever a change has been made.

If the intention is to have users connect to the database using their own connection unique Oracle (a fine idea, assuming that your application takes advantage of something like authentication for the proxy to the middle layer), you can use Oracle VPD (database virtual private) to restrict the data set in the unique schema who owns all objects to ensure that users can only see their own data.

    When something like you describe is reported, most often the user does not understand the layers of high level exist across all pages and updates on the page of your site. If you delete "Layer 1" you may remove the content of all pages of your site.

  • Best version of PS for Web design

    Hello! I'm a budding web deisgner. What is the best version of photoshop that have the features necessary to complete Web design projects quickly and accurately?

    For web design, I think that the full version of photoshop or elements will work fine. Elements will make more hand holding with assistants, etc., but her brother has more power without holding a hand. Meaning that it can take more than a few steps, but more as a profession can normally do off.

    What neither can do is svg graph, which would require illustrator and/or edge animate. (Normally graphics are created in illustrator and animated on the edge)

  • The image exceeds the size to make save for Web and devices has been designed

    I just upgraded from CS3 to CS5. I assumed that save for Web & devices would have been redesigned so that it would not complain with modern large pictures they were just too big!

    However, it still doesn't work. I just do not get it. Photoshop in general now is editing of very large images. It should be able to manage them also in this function.

    Is this just a legacy message, or is it really true that this feature can only manage small images?

    Save for web is designed to optimize the web graphics by squeezing the bytes while retaining the quality.  It was not intended to scale and then optimize large images. This is shown in the alert message.

    You can present a feature request to Adobe to change the original intent of SFW.

    SFW can display 4 versions of an image in different types of optimization. We must save the 4 temporary files. Imagine trying to save a huge image 4 times at a time through the "File-Save As. That's why you see this warning message. It takes time to build these temporary files, especially when you throw a huge file at home.

    Consider a solution scripted this one where a copy of your image is first reduced and then transferred to SFW.

  • BlackBerry smartphone how to stop email account Gmail - but keep it registered for the calendar?

    I have a secondary e-mail (Gmail) account that I use for my Google Calendar, so I need to save to maintain synchronized calendar on my Blackberry.

    But I don't want emails from this account sent to my Blackberry.  (Emails from this account are already sent to my main account, so now I get double e-mails on my Blackberry which is irritating, especially since they come from different times.)

    How can I stop my Blackberry to get e-mails from the account side, while keeping this one only for the calendar?

    Thanks for the tips!

    BTW, I prefer not to rely on or to pay for an app of the add-on. I guess it's a feature of basic Blackberry that I just can't understand.  I have also tried my provider, Verizon, Web site, but found nothing relevant.

    OK, not difficult at all.

    Set up your gmail account to push the BlackBerry, as it looks like you already have.

    Now, back to the account setup BIS, where you entered your email and password for this account and click the FILTERS.

    Choose notto transfer messages to the device. The change is saved automatically.

  • Output with uniform colors for web pages

    This color management really important issue which does not seem to be adequately handled by the Illustrator. I hope I'm missing something, but I'm afraid that I'm not.

    When you design a webpage in Illustrator, unless you're actively in view > proof Set > sRBG every time you open the document, in hexadecimal values selected objects will not match between the display of your document and the browser. On the other hand, save for Web, default will convert colors sRGB for you, so display them faithfully in the design.

    So, if you're not in the process of think to select sRGB format of test, whenever you open your document, and then once you start to produce for the web, images are, but do not have the background and text color. AND there is no way to convert the document at the end of the process to have the color values appropriate as far as I can tell.

    At this point, your only option is to make a save for Web on your overall design, converted it to sRGB which way, open the raster file in photoshop and select the hex colors from there.

    It seems at the very least, you should be able to set a default evidence for a document configuration, or be able to select the hexadecimal values converted for you to sRBG.

    I missing something here, or is this an accurate description of the situation?

  • "Save for Web" crashes PS Elements

    "Save for Web" does not work in Photoshop Elements. It is shocking that such a fundamental thing because it blocks the software!

    My reason for buying PS Elements was for Web design. Now I have a value of $100 from software that is of no use to me either.

    There has been no PS Elements update in the months + since I downloaded this software from the Apple App Store.

    I suggest you to remove the preferences of the plugin to application of PES.

    You can find the preferences of the plugin to the mentioned location below...

    Come on in ' ~ / Library/Containers/com.adobe.pse11editor/Data/Library/Preferences/Adobe/Plugins '. Inside this folder, you will see a folder 'Adobe save for Web Elements 11'. Please remove this folder and then restart PSE.

    Now, you will be able to use save for Web.

    Hope this would help you.

    See you soon!

  • CS6 save for Web image size limit (retina)

    I have been designing of many these days, sites especially mobile: iphone Retina (640w).  Most of the time, these designs can be long in the tooth with the height of these documents - more than 8000 pixels sometimes.  I noticed that 8000 pixels is the threshold limit for export "save for web".  Nothing more of 8000 pixels will be downgraded in quality on the features of the retina by reducing the image.  Jpg will be always the right height and width, but seen on an iphone, you can easily see the degradation.   Images and text are blurry.  It is no good trying to show a customer what their site on an iphone will look like.

    So my question is, is there a work around?  A preference to be changed?  Am I missing something to get the full quality of my design comp to preserve the quality of retina display?

    Conroy, it is incorrect for the cases I have provided.  Save for the web will save dimensions width and height appropriate for retina ios devices.  as paul said, SFW will save up to 30 000 pixels.  the problem was that "progressive" was not checked for extreme cases to appear correctly on the iphone.

    both models have been exported using SFW:

    progressive:

    not progressive:

    the two look identical on the desktop.

  • How to 'save for web' with information from a dataset

    I created psd to design web page set up with a master image.  The main image is defined as a pixel replacement variable and uses a dataset to load in images of a local folder.  I have more than 100 images in this folder and I need to resize the image to 250 pixels wide and "save for web".   Resizing and registration is easy with an action, but the thing, it's that I need to use a different column in my DataSet as the name of the saved files.

    Is it possible to create an action that will loop through each row in my dataset, do the replacement of pixel on the image, enter the name of the file in the next column, flatten & resize the image and then save it as the file name?  Of course, would cancel the flattening and resizing to start on the next line.

    I guess I could break in two actions.  One who reads the dataset, to replace the pixels and export for the web with the new file name.  Then I could set up a second action to run in batch on the folder that contains the images recently exported and just resize all the.

    I don't know how (if it is even possible) is to loop through the dataset by using the action, get the variable of the object dataset for file name and export for the web with that name.  Any ideas?  Thank you.

    Here's a function I use. With this function, you can import a CSV dataset to your document. Get names of groups of data csv form. Then in a loop applies a set of data by name, and then save as in any format you like. The loop repeats until all sets of data are processed.

    fileImportDataSets = function( file ) {
        var desc = new ActionDescriptor();
            var ref = new ActionReference();
            ref.putClass( stringIDToTypeID( "dataSetClass" ) );
        desc.putReference( charIDToTypeID( "null" ), ref );
        desc.putPath( charIDToTypeID( "Usng" ), new File( file ) );
        desc.putEnumerated( charIDToTypeID( "Encd" ), stringIDToTypeID( "dataSetEncoding" ), stringIDToTypeID( "dataSetEncodingAuto" ) );
        desc.putBoolean( stringIDToTypeID( "eraseAll" ), true );
        desc.putBoolean( stringIDToTypeID( "useFirstColumn" ), true );
    executeAction( stringIDToTypeID( "importDataSets" ), desc, DialogModes.NO );
    };
    function applyDataSet(setName);{
        var desc = new ActionDescriptor();
            var setRef = new ActionReference();
            setRef.putName( stringIDToTypeID( "dataSetClass" ), setName );
        desc.putReference( charIDToTypeID( "null" ), setRef );
    executeAction( charIDToTypeID( "Aply" ), desc, DialogModes.NO );
    };
    function getDataSetNames(csvFileRef) {
        _ftn = function(string){
        var csvItems = string.split(",");
        datasetName = csvItems[0]
        return datasetName;
    };
    csvFileRef.open();
    var datasetArray = new Array();
    var i = 0;// assumes the dataSet name is the first field
    while (csvString = csvFileRef.readln()) {
       if (csvString.length < 2) continue; // Skip empty lines
      datasetArray[i] = _ftn(csvString);
      i++;
    }
    csvFileRef.close();
    return datasetArray;
    } 
    
    //sample usage
    var csvFileRef = File.openDialog("Please select CSV file");
    var datasetNames = getDataSetNames(csvFileRef);

  • Photoshop or Fireworks for Web Logos?

    Hello

    I recently designed a logo for my friend Don Demaise's Web site: http://www.landcreationsnj.com

    I used Fireworks for the logo. Photoshop would be a better choice for web logos?

    Bob

    Pixels are pixels. Nobody care about how they were created, especially just for web use when nothing else needs to be considered. Use what you're comfortable with and spend your time on learning design rather another graphics program. If I can be frank: this 'logo' isn't bad...
